Abstract Seismic hazard refers to the potential for earthquakes to occur in a particular area and cause damage, based on factors such as the frequency, magnitude, and location of past earthquakes, as well as geological conditions. Areas with high seismic hazard may experience more frequent and/or more intense earthquakes, making it essential for residents and authorities to take appropriate measures to reduce the risk of damage and loss of life. Seismic disaster mitigation involves implementing measures to reduce the impact of earthquakes on human life, infrastructure, and the environment. These measures aim to minimize casualties, injuries, and property damage by enhancing preparedness, improving building codes and construction standards, implementing land use planning, and developing emergency response plans. Seismic disaster mitigation technique is being adopted which causes reduction in earthquake forces by different methods. The proposed paper investigates the ability of base isolation and energy absorption system using lead rubber bearings and fluid viscous dampers to protect the structure by controlling seismic response. Concrete building structures of regular type with various plan dimensions have been modelled in SAP 2000 for story heights of G+5 and G+15. Non-linear Time history method has been performed for both conventional and buildings with isolation and damping system. Seismic responses e.g. base shear, max drift / displacement etc. have been compared for the conventional and isolated / damped structures of different aspect ratio (plan / height) for each of the building models with same seismic considerations.
